SPF, which is short for Sender Policy Framework, is an e-mail security system, which is is intended to verify if an e-mail message was sent by a certified server. Employing SPF protection for a domain name will stop the forging of emails created with the domain. In simple words: activating this function for a domain name creates a specific record in the Domain Name System (DNS) that contains the IP of the servers that are allowed to send email messages from mailboxes under the domain. When this record propagates worldwide, it will exist on all the DNS servers that route the Internet traffic. Every time an e-mail message is sent, the first DNS server it uses tests whether it originates from an official server. In the event it does, it's forwarded to the destination address, however when it does not come from a server listed in the SPF record for the particular domain, it's discarded. Thus nobody will be able to mask an email address then make it look as if you are sending spam messages. This technique is also known as email spoofing.

SPF protection can be enabled for any domain name hosted in a cloud website hosting account on our cloud hosting platform with no more than a few clicks. The function is available in the Emails section of our cutting-edge Hepsia Control Panel and all you need to enable it is to pick one of your domains from the drop-down list and to type in the hostnames together with the IPv4 or IPv6 addresses of the mail servers that will be certified to send email messages from your emails. As an additional option you may also restrict the messages to be sent from your domain name only if it has our MX records, i.e. when our servers handle the e-mail addresses for it, not a third-party supplier. This feature provides you with the highest degree of safety, but it is not applicable if only your web site is on our servers while your email addresses for the domain name are handled somewhere else. Regardless, the SPF protection service will keep your emails protected from being used for spam or scam purposes.
